Problems solved by technology
Once the IGBT module is damaged, the entire system will no longer work normally, which is undoubtedly fatal for some occasions with high power requirements, and if the damaged IGBT module still works as usual, the entire system will be greatly reduced. Therefore, it is necessary to detect the damage state or damage state of the IGBT module in real time

The invention discloses a state detection system of an IGBT (Insulated Gate Bipolar Translator) module. The system comprises a driving power detection module and a control center, wherein the driving power detection module is connected between the driving power supply module and the power supply isolation module, the power supply isolation module is connected with the IGBT module, and the control center is connected with the output end of the driving power detection module; the driving power detection module is used for detecting the driving power provided for the IGBT module by the driving power supply module; and the control center is used for generating a state detection result of the IGBT module after receiving the driving power. According to the IGBT module state detection system provided by the invention, whether the IGBT module is in a damaged state or not can be determined by detecting the driving power provided for the IGBT module by the driving power supply module, and the IGBT module state detection system has important significance in guaranteeing the reliability of the system and is suitable for large-scale popularization and application.
Description
technical field [0001] The invention relates to the technical field of power electronics, in particular to a state detection system of an IGBT module. Background technique [0002] After long-term development, my country has become the world's largest energy producer and energy consumer. At present, my country's energy sources are mainly hydropower, nuclear power, solar power, wind power, natural gas, coal and so on. According to the data of the National Bureau of Statistics, my country's coal consumption will account for 56.8% of the total energy consumption in 2020, and the proportion will drop by 0.9% over the previous year. The proportion is increasing year by year. In the first three quarters of 2021, primary power production such as industrial hydropower, nuclear power, wind power, and solar power generation above designated size accounted for 29.2% of the total power generation, an increase of 0.9 percentage points over the same period of the previous year. With the g...
